I agree skulboy, bold and simple can be really nice. When I think of it, that's probably what I like the most. I just didn't want to feel obligated to do simple prints only because I didn't know how detailed they can be.

constructive input: I think the solid areas of the wave might bubble.. too large a surface of foil and air gets trapped, bubbles the foil, it doesn't stick and tears. innovas specs say no solids greater than 18pt diameter. when in doubt I drag an 18pt circle around to check. all it needs are air holes within the large solid. I'd just throw some negative turbulence in there.
